your configs are a bit overkill, but nothing too bad about them; I'd try this for the client config:
client
dev tun
proto udp
remote x.x.x.x 9200
resolv-retry infinite
nobind
tun-mtu 1500
tun-mtu-extra 32
mssfix 1400
ping-timer-rem
comp-lzo
cipher BF-CBC
auth SHA1
keysize 512
reneg-sec 0
win-sys env
route-method adaptive
verb 3
auth-retry nointeract
ca ca.crt
auth-user-pass pwd.txt
i.e. remove the 'port', do not bind, remove the 'mute-replay' warnings.
also, you don't need to use 'tun-mtu-extra 32' unless you really know what you're doing, but this needs to be removed on both ends.
